[Geodynamics] EGU 2019: Lithosphere and Upper Mantle Heterogeneities Shaping Surface Deformation and Subduction Dynamics GD5.4/SM4.15/TS9.12

[Roberta Carluccio]

Dear colleagues,

we would like to draw your attention to the *EGU* session
*GD5.4-SM4.15-TS9.12* (co-organised):


"*Lithosphere and Upper Mantle Heterogeneities Shaping Surface Deformation
and Subduction Dynamics*."


This session aims to highlight recent advances in constraining the scales
and amplitudes of heterogeneities in the lithosphere as well as their
dynamic role. We welcome multidisciplinary contributions from different
fields of geophysics and geology.


To submit an abstract please follow the link
https://protect-au.mimecast.com/s/1IMkCROAQotXAOxrf99Sic?domain=meetingorganizer.copernicus.org. The deadline
for abstract submission is January 10th.



We look forward to seeing you in Vienna!

Kind regards,



Conveners:

Roberta Carluccio, University of Melbourne

Fabio A. Capitanio, Monash University
Lorenzo Colli, University of Houston
Nathan Simmons, Lawrence Livermore National Laboratory



On behalf of the conveners,

Roberta


*EGU* session *GD5.4-SM4.15-TS9.12*: "*Lithosphere and Upper Mantle
Heterogeneities Shaping Surface Deformation and Subduction Dynamics*."

The lithosphere, the outermost shell of the Earth, constitutes the upper
thermal boundary layer of mantle convection. It is well established that
its properties play a central role in the development of solid Earth
dynamics. Through its properties the lithosphere also provides a primary
source of thermal and chemical anomalies for mantle convection when it is
injected in the mantle as subducting slabs. Here, the subduction of cold
and dense oceanic lithosphere into the underlying mantle acts as the major
driving force of plate motion, and as a key component of the water and
carbon cycles throughout the Earth. At the global scale, some of these
lithosphere heterogeneities include rheological stratifications, sutures,
fracture zones, and lateral and vertical variations in temperature and
composition. These exist at various scales and play a major role in
determining subduction dynamics and the degree of lithosphere-mantle
decoupling. Deciphering the interaction of the lithosphere with the
underlying asthenosphere and deeper mantle is critical to understanding the
secular evolution of the Earth system and to reconcile models with natural
observations. This session aims to highlight recent advances in
constraining the scales and amplitudes of heterogeneities in the
lithosphere as well as their dynamic role. We welcome multidisciplinary
contributions. Some key areas of interest are lithospheric structure and
morphology, subduction kinematics and dynamics, slab-mantle interaction and
slab deformation, active margin tectonics and subduction-induced seismicity.
